两台F1060防火墙做irf后，上联宽带分线交换机的口该配置成2层聚合口吗？

冗余组典型配置举例

2.5.1  工作在三层，上下行分别连接两台路由器，两台路由器接口不在同一网段

1. 组网需求

·            如图2-4所示，Device A和Device B组成IRF，Router 1和IRF相连的接口与Router 2和IRF相连的接口不在同一网段，Router 3和IRF相连的接口与Router 4和IRF相连的接口不在同一网段。

·            正常情况下，流量走Router 1——Device A——Router 3；当这条通道上的任一链路或者设备故障时，流量切换到Router 2——Device B——Router 4。正常通道故障恢复时，流量再切回。

2. 组网图

图2-4 配置组网图

3. 配置步骤

如图2-4所示，配置各接口的IP地址、路由、安全域及域间安全策略，保证网络可达，具体配置过程略。

配置IRF

# 配置IRF端口1/2，并将它与物理端口GigabitEthernet1/0/3绑定，并保存配置。

<DeviceA> system-view

[DeviceA] interface GigabitEthernet 1/0/3

[DeviceA-GigabitEthernet1/0/3] shutdown

[DeviceA-GigabitEthernet1/0/3] quit

[DeviceA] irf-port 1/2

[DeviceA-irf-port1/2] port group interface GigabitEthernet 1/0/3

You must perform the following tasks for a successful IRF setup:

Save the configuration after completing IRF configuration.

Execute the "irf-port-configuration active" command to activate the IRF ports.

[DeviceA-irf-port1/2] quit

[DeviceA] interface GigabitEthernet 1/0/3

[DeviceA-GigabitEthernet1/0/3] undo shutdown

[DeviceA-GigabitEthernet1/0/3] quit

[DeviceA] save

[DeviceA] irf-port-configuration active

# 为确保Device A与Device B在主设备选举过程中，Device A为主，修改Device A成员优先级为2（成员优先级大的优先，缺省情况下，设备的成员优先级均为1）。

[DeviceA] irf member 1 priority 2

# 激活IRF端口下的配置。

[DeviceA] irf-port-configuration active

配置Device B

# 将Device B的成员编号配置为2，并重启设备使新编号生效。

<DeviceB> system-view

[DeviceB] irf member 1 renumber 2

Renumbering the member ID may result in configuration change or loss. Continue? [Y/N]:y

[DeviceB] quit

<DeviceB> reboot

# 参照图2-4进行物理连线，重新登录到Device B，配置IRF端口2/1，并将它与物理端口GigabitEthernet2/0/3绑定，并保存配置。

<DeviceB> system-view

[DeviceB] interface gigabitethernet 2/0/3

[DeviceB-GigabitEthernet2/0/3] shutdown

[DeviceB-GigabitEthernet2/0/3] quit

[DeviceB] irf-port 2/1

[DeviceB-irf-port2/1] port group interface GigabitEthernet 2/0/3

You must perform the following tasks for a successful IRF setup:

Save the configuration after completing IRF configuration.

Execute the "irf-port-configuration active" command to activate the IRF ports.

[DeviceB-irf-port2/1] quit

[DeviceB] interface GigabitEthernet 2/0/3

[DeviceB-GigabitEthernet2/0/3] undo shutdown

[DeviceB-GigabitEthernet2/0/3] quit

[DeviceB] save

# 激活IRF端口下的配置。

[DeviceB] irf-port-configuration active

配置Track，监测上、下行接口的物理状态。

<DeviceA> system-view

[DeviceA] track 1 interface gigabitethernet 1/0/1 physical

[DeviceA-track-1] quit

[DeviceA] track 2 interface gigabitethernet 1/0/2 physical

[DeviceA-track-2] quit

[DeviceA] track 3 interface gigabitethernet 2/0/1 physical

[DeviceA-track-3] quit

[DeviceA] track 4 interface gigabitethernet 2/0/2 physical

[DeviceA-track-3] quit

配置冗余组。

# 创建Node 1，Node 1和Device A绑定，为主节点，成员接口为GE1/0/1和GE1/0/2。关联的Track项为1和2。

[DeviceA] redundancy group aaa

[DeviceA-redundancy-group-aaa] node 1

[DeviceA-redundancy-group-aaa-node1] bind slot 1

[DeviceA-redundancy-group-aaa-node1] priority 100

[DeviceA-redundancy-group-aaa-node1] node-member interface gigabitethernet 1/0/1

[DeviceA-redundancy-group-aaa-node1] node-member interface gigabitethernet 1/0/2

[DeviceA-redundancy-group-aaa-node1] track 1 interface gigabitethernet 1/0/1

[DeviceA-redundancy-group-aaa-node1] track 2 interface gigabitethernet 1/0/2

[DeviceA-redundancy-group-aaa-node1] quit

# 创建Node 2，Node 2和Device B绑定，为备节点，成员接口为GE2/0/1和GE2/0/2。关联的Track项为3和4。

[DeviceA-redundancy-group-aaa] node 2

[DeviceA-redundancy-group-aaa-node2] bind slot 2

[DeviceA-redundancy-group-aaa-node2] priority 50

[DeviceA-redundancy-group-aaa-node2] node-member interface gigabitethernet 2/0/1

[DeviceA-redundancy-group-aaa-node2] node-member interface gigabitethernet 2/0/2

[DeviceA-redundancy-group-aaa-node2] track 3 interface gigabitethernet 2/0/1

[DeviceA-redundancy-group-aaa-node2] track 4 interface gigabitethernet 2/0/2

[DeviceA-redundancy-group-aaa-node2] return

配置会话热备

# 为确保当主成员设备故障，业务不中断地切到备成员设备，需配置会话热备功能。

<DeviceA> system-view

[DeviceA] session synchronization enable

4. 验证配置

缺省情况下的显示信息

# 显示冗余组信息。可以看到优先级高的Node 1为主节点，Node 1和Node 2下面的成员接口都处于UP状态。
